I'll be brief. Today I upgraded my Win xp to Win 7. After the installation, my liiijnz suffered a huge fps drop (from 100-120 to 40). I did some tests but I was unable to fix this. I have 4Gb Ram on my computer but only 3 were available. It was "normal" with Win xp 32bit but It isn't with Win 7 64bit so i thought "fix this meanwhile". I googled for a while and then, from the bios (I have an Asus P5B Deluxe) I enabled the memory remapping option. Wohoo 4Gb available, the funny thing is that also liijnz was fixed and the fps, from the same tower of gorge, changed from 40 to 175 \o/ This is going to be useless to the most of you but maybe there's someone else out there with this problem so..
